Week 2: Tutorial 1 - the First program

To start the first program, open Jedit, then copy & paste the following code:


public class HelloWorld {
      public static void main(String[] args) {
          System.out.println("Hello, World");
     } 
}


Save the code as the file named HelloWorld.java
Go to cmd windows in Windows OS or open terminal on MAC OS, then type


> javac HelloWorld.java


> java HelloWorld


See the output on the screen


Do the following exercises:


1. Replace "HelloWorld" by "Your name", then make a new line 
System.out.println("We are SS-1201 students at the Faculty of Science, Universiti Brunei Darussalam");
2. Replace println by print 
3. Use the println and print to make a STAR formation of symbol *
4. Try to remove ; from System.out.println("Hello, World"); save and compile the code to see the error!
5. Try to remove the inner bracket {}, save & compile the code to see error!
